ANTIRATTLE DOOR-LATCH.

Specification of Letters Patent.

Patented @Ich Ml, 19919.

Application filed May 26, 1919. Serial No. 299,779.

To all whom t may concern Be it known that I, WILBUR R. HERBY, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Antirattle Door-Latches, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to anti-rattle door latches, and, as here shown, has for its particular object t provide a simple, eEective anti-rattle door latch for automobiles or the like, which will act as a compensating element for the play or lost motion normally found in door latches of this character, and also for wear and` displacement of the parts resulting from use.

It is an object of the invention to provide a design of an anti-rattle door latch consisting of few parts which can be cheaply manufactured, which is simple and substantial in its mechanical organization and which will not readily be broken or rendered out of adjustment by hard usage such as door latches of automobiles receive.

While as here shown my improved latch lthe invention.

In the accompanying drawings:

Figure 1 is a side elevation of my improved latch as assembled in the body of an automobile.

Fig. 2 is a horizontal cross sectional view taken on the line 2-2 of Fig. 1; and' Fig. 3 is a vertical cross sectional view taken on the line 3-3 of Fig. 2.

In the drawings the anti-rattle latch is shown assembled in the door 1 andadjacent body portion 2 of an automobile, and consists of the usual latch bolt 3, which may be yieldingly or slidably mounted in the door 1 in any suitable manner, and rovided with any suitable knob or finger ever 4?, by which the latch bolt may be retracted to open the door, the bolt being normally projected outwardly by a spring element 5 in the usual manner.

In the edge of the door aperture in the body of the automobile, adjacent vthe ed of the door in which the latch bolt 3 1s located, is a suitable keeper casing 4 having open spaces 5 and 6 therein spaced apart by a partition 7; the partition having an aperture 8 therein through which a spring plunger 9 operates. The plunger 9 contacts with the end of the latch bolt 3 which pro,- jects into the space 5, and is held in contact with the latch bolt when the door is closed by a spring 10 interposed between the plunger and the outer wall of the casing 4; the plunger being provided with a flange 11 which acts to limit the movement of the plunger in one direction. The casing 4 is provided by projecting edges or flanges 12 having screw holes therein by means of which the casing is secured to the body of the car, the edge of the door aperture .in which the casing is secured being depressed in a suitable manner so that the outer face of the housing is substantially flush with the edge.

From the foregoing detailed description the construction and operation of my improved door latch will be understood, it being obvious that the action of the s ring plunger 9 upon the latch bolt 3 will e to prevent lost motion or chattering of the same when the automobile isin operation. The spring tension on the latch bolt is preferably suicient to project the same forward under the spring plunger when the door is slammed shut, and of course, the latch bolt may be projected lunder lthe plunger by operating the door handle.

The plunger 9 has suflicient longitudinal movement and spring tension excited thereon to compensate for all ordinary wear and displacement of parts and will thus act at all times to prevent rattling for chattering of the latch bolt within the latch s ace 5 and thus prove in all respects an e ective anti-rattle device.

For general use the anti-rattle latch ma be made in such sizes and. shapes as wi meet the general requirements.

Having thus fully described my invention, what I claim as new and desire to secure by Letter Patent, is

1. In a door latch, the combination, with a keeper casing having a partition forming a plurality of spaces in said casing, of a latch bolt coperating with said casing and adapted to be projected into one of said spaces, a spring plunger supported upon and extending through said partition and contacting with the latch bolt whereby to yieldingly press the same against said casing.

2. In a door latch, the combination, with the latch bolt whereby t o yieldingly press the same against said casing.

3. In a door latch, the combination, with a keeper casing having a partition forming two oppositely disposed spaces therein, of a latch bolt coperating with said casing and adapted to be projected into one of said spaces, a spring actuated plungler operable in the other space and adapte to contact with the latch bolt whereby to yieldingly press the same against said casing.

4. In a door latch, the combination, with a keeper casing having a partition forming a plurality of spaces therein separated b a partition, of a latch bolt coperating wit sald casing and adapted to be projected into one of said spaces, a spring actuated plunger operable in the other space, having a limit of movement stop cooperating with said partition, and adapted to contact with the latch bolt to prevent rattling thereof in said casing.

5. In a door latch, the combination, with a keeper casing havin a partition forming a plurality of spaces t erein, of a latch bolt coperating with said casing and adapted to be projected into one of said spaces, a spring actuated plunger operable in the other space and coperating with the latch bolt to prevent rattllng thereof and having 'means' to compensate for wear and variable adjustment of said parts.

In testimony whereof I aiix my signature.

WILBUR R. HERBY.
